Product details
Overview
R5F100GGDFB#X0 from Renesas is a 48-pin LFQFP-packaged RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB data flash, 8 KB RAM, and industrial-grade operation up to +105°C. It delivers 41 DMIPS at 32 MHz, consumes 66 μA/MHz active and 0.57 μA in RTC+LVD-only mode, and integrates UART, I²C, SPI, 16-bit timers, 10-bit ADC (26 channels), and real-time clock for embedded control in power-constrained industrial systems.
For engineers reviewing the R5F100GGDFB#X0 datasheet, R5F100GGDFB#X0 pinout, R5F100GGDFB#X0 application, or R5F100GGDFB#X0 equivalent, key selection criteria include its 48-pin LFQFP-0.5mm package, G-grade temperature range (−40°C to +105°C), integrated data flash with 1M rewrite cycles, low-power STOP/HALT/SNOOZE modes, and hardware multiplier/divider supporting signed/unsigned arithmetic.
Technical Context
The R5F100GGDFB#X0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). Its memory subsystem includes 128 KB on-chip code flash (1 KB block size), 8 KB data flash with background operation (BGO), and 8 KB RAM - all accessible within a 1 MB address space.
Peripherals are tightly coupled to low-power operation: the 10-bit ADC supports up to 26 analog inputs with internal 1.45 V reference and temperature sensor; the real-time clock provides calendar functionality (99-year range), alarm, and clock correction; and serial interfaces include up to 10 I²C channels, 4 UART/LIN channels, and 8 CSI (SPI-compatible) channels - all configurable without external components.
